Thanks all! Sprocket got here last evening. He's pretty sweet if I do say so myself.
I know he is a chinesey, but holy moley he is a long long long hamster!
He loves his bin and seems much braver than Pumpkin. Once he's out of quarantine I'm excited to get to know him more. He's not "friendly" but he is happy to be held and I'm sure once he realises he gets lots of yummy treats from us, he'll warm up.
